The patent includes claims to an enhanced type of steam vapor that can effectively kill a broad range of microorganisms within 3-5 seconds, reduce surface-mediated infection risks and serve as a green, more effective alternative to chemical disinfectants, the release stated.

Rick Hoverson, principal of AVT, said: "We are very pleased and excited that the U.S. Patent and Trademark Office has awarded a patent to this important process. This patent confirms that the TANCS process is new and unique, and that not all steam is created equal. Using ''tap water'' as a disinfectant has a number of terrific benefits that directly relate to maintaining a healthy indoor environment, sustainability, reduced waste streams, simplified application protocols and cost reductions."

The TANCS steam vapor system works by facilitating the redistribution of charges between the water molecules and dissolved mineral components naturally found in potable tap water and transforming it into super-heated low-moisture steam, the release noted.

By eliminating the need for highly toxic chemistries, the TANCS steam vapor system dramatically reduces the negative environmental impact of disinfection while allowing it to be performed in environments and areas where it previously may not have been a viable solution, the release added.
